Page 2: Specification
Description: This kit contains the required components to build yourself a petroleum gas detector. This module is based on a LM393 I.C. and a MQ5 sensor. While being a simple soldering project for beginners, this kit can be used in a variety of small personal, educational or enterprise applications such as: Liquid Petroleum Gas Detector for 5v Microcontrollers (Analog/Digital) Natural Gas Detector for 5v Microcontrollers (Analog/Digital) -

Bill of Materials: This package includes 23 pieces which are listed below along with their labels and quantity. Quantity Component Label Value / Type / Label 47Ω / (Yellow, Violet, Gold, Gold) R2, R5, R6, R7, 1KΩ / (Brown Black, Red, Gold) R9, R10 10KΩ... - Page 4 Assembly: 1) In order to assemble the module, you need the following tools: *It is recommended to have some isopropyl alcohol and a fine soldering brush handy to clean off the excess flux on the circuit board when the soldering is done. *ATTENTION* DO NOT USE RUBBING ALCOHOL, IT WILL DAMAGE THE COMPONENTS.
- Page 5 b) The soldering iron temperature depends on the type of solder used. If you are using a typical 60/40 lead solder, depending on the thickness the temperature should be set anywhere between 370 to 500 °F (187 to 260 °C). If you are using a lead-free solder, increase above temperatures by 40 to 70 °F (5 to 20 °C).
- Page 6 To begin the assembly process, insert the LM393 as shown in the photo. Ensure the notch of the Integrated Circuit aligns with the markings on the board, also known as the silkscreen. All soldering will be done on the backside of the board. You may proceed to solder the resistors in place by following the numbering on the board and placing the correct color resistor...
- Page 7 Insert the transistor as shown in the picture. Ensure the transistor matches the outline of the silkscreen. Please pay attention to the IC number of the transistors as they both have different functions and must go in the correct place for this circuit to work! Insert the 3mm LED as shown in the image.
- Page 8 You may proceed to solder the blue potentiometer, then proceed to solder the black buzzer and the four-pin header. For the MQ5 element, it is recommended to solder the element with the label facing inwards towards the resistors. On the provided daughter card, solder the remaining resistor in the kit with the color band sequence: Red, Red, Yellow Gold on the two through-hole pads as shown.
- Page 9 This secondary PCB is designed with the audio chip integrated. You have two options to solder this component. Option 1: As shown in the photo, solder the daughter board on the backside of the board. To install in the correct orientation, use the MQ5 solder point for reference.
- Page 10 The second method to use this module is to connect the third pin to Arduino analog pin and use analog read sketch to read the values from this module. This example code can be found in the Arduino IDE under File>Examples>Basics>AnalogReadSerial.
